| Abstract: | Atmospheric temperature oscillations at similar frequencies have been detected in the spectra of variations in the rotational temperatures of the OH and O2 nighttime emissions, simultaneously observed at two spaced stations in the range of periods ～1–3 h. These oscillations are probably caused by global waves: short-period solar tides and/or free oscillations of the atmosphere. |
